multiple once for the same subscriber

[igniscom]

It seems that if I subscribe twice to the same channel with the same subscriber with the "once" method, then if I "publish", the channel will be executed twice for the subscriber !

I thought "once" would have meant :

• one subscription by subscriber, avoiding multiple subscriptions for the same subscriber.
• when published once, then unsubscribed (that part is ok).

Example :

mediator.once("test", function () { print("Hello world!"); });
mediator.once("test", function () { print("Hello world!"); });
mediator.publish("test");

...seem to print :

"Hello world!" "Hello world!"

I believe it is working as intended. Calling once, or any other subscribing function, creates a new instance of a Subscriber. So each subscriber is different, no matter if you pass in the same arguments. It is not the same subscriber being called twice, but two different subscribers being called once.
